Knapp PW, Keller RA, Mabee KA, et al. - The present study was conducted to evaluate patient engagement with application-based educational tools and to explore what content was most useful to patients in the perioperative period surrounding total hip arthroplasty (THA) and total knee arthroplasty (TKA), respectively. Between October 2017 and January 2020, patients undergoing THA and TKA were included to use an application-based digital technology. A total of 207 patients were included in this study, 95 (46%) had undergone THA, and 112 (54%) underwent TKA. Patients had a high rate of compliance when presented with educational material related to THA and TKA. The data illustrate that digital technology platforms provide a scalable, meaningful approach to engaging patients throughout the continuum of joint replacement care and may serve as a cost-effective adjunct to traditional methods.
